How do you remove unintentional iodine stains from white gold?
With difficulty. But try rubbing with strong sodium thiosulphate
solution (photographic hypo) You see, iodine doesn’t just stain the
metal, but actively combines with it to form an iodide complex. But
hypo does remove the colour from iodine stains. Anyway, it certainly
won’t do any harm even if it doesn’t do any good. > – John Burgess;
